What is "bryophyllum"

Bryophyllum (from the Greek bryon/bryein = sprout, phyllon = leaf) is a plant genus of the Crassulaceae family that has sometimes been included within the genus Kalanchoe. There are about forty species in the group, native originally of South Africa, Madagascar, and Asia. The group is notable for vegetatively growing small plantlets on the fringes of the leaves; these eventually drop off and root. These plantlets arise from mitosis of meristematic-type tissue in notches in the leaves.

Nowadays, bryophyllums are naturalised in many parts of the tropics, and deliberately cultivated for their attractiveness or for their interesting reproduction.
